Abstract
A cast aluminum base frame of a movable guide for a timing chain in an internal combustion engine is produced by a die in which the parting lines are located so that the shoe-engaging surface of the base frame and the pivot shaft-receiving hole are each formed by a continuous surface of the die, without oppositely pitched drafts.
